Asclepias macrotis Torrey (Long Horned Milkweed)

Family: Asclepiadaceae

Status: Native

Synonyms:
None

Asclepias macrotis is easily recognized by its long, filiform leaves with reflexed margins and its greenish white flowers. It is a rather delicate looking plant for an Asclepias. The base is quite woody (suffrutescent) and it usually has only 1-5 flowers per umbel. The long horns on the hoods are quite obvious. Asclepias macrotis is found rather infrequently in the Gila, in rocky draws or limestone ridges.
